Combination of the gene-expression classifier (GEC), with its high negative predictive value, and the BRAF mutation test, with its high specificity, might have a synergistic effect in the diagnosis of thyroid nodules with indeterminate cytology. However, Kloos et al. demonstrate that the BRAF test is of no additional benefit in nodules categorized as 'benign' by GEC.
